CLINCH COLLAR FOR SHADES.

Application filed October 8, 1926.

This invention relates generally to electric light fixtures and more particularly to a collar adapted to be attached to a glass shade which is supported upon or by the electric lamp, the threaded end of the electric lamp being screwed into the standard socket connection. I

Heretofore it has been the general practice to construct the glass shades with a lip and the shade is usually supported by inserting this lip into a collar carried by the lamp socket and provided with set screws for securing the shade in place. The lips of shades are easily broken rendering the entire shade unusable. F unthermore, in the fabrication of shades with lips there is considerable loss due to breakage or defective lips.

The present invention contemplates the elimination of the lip from the shade and has for its object to provide a collar readily attachable to the lipless shade. and having a fiberor composition ring connected thereto for direct contact with the electric lamp thereby rendering the device safe and serviceable. Another object of the invention is to pro vide a ring embodying these characteristics which can be cheaply fabricated.

The invention consists in the novel features of construction and in the manner of combining or arranging the same all of which will be fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of this specification Fig. 1 is a sectional elevation showing the practical use of my invention; Fig. 2 is a detail sectional view of the ring on the line 2-2 of Fig. 3; Fig. 3 is a top plan view, Fig. 4 is an inverted plan view and Fig. 5 is an enlarged detail sectional view.

Referring to the drawing, 10 indicates the standard incandescent lamp and 11 the threaded metallic end thereof, this threaded metallic end being normally screwed into a socket 12. 13 indicates a lipless glass shade to which is attached my improved construction of ring 14 carrying the inner fiber ring 15. The ring 14 is made of thin sheet metal and comprises the inclined flange portion 16 which is adapted to rest upon the exterior of the shade. The ring is given a return bend at 17 and then carried inwardly as indicated at 18 to provide a seat for the fiber or composition washer or lining 15 and it will be noted that this fiber washer or lining is provided with a notch 20 to accommodate the bead of Serial No. 140,250.

solder 21 which appears on all. of the standard incandescent bulbs.

The inwardly projecting seating flange is formed with tongues 22 which are punched therefrom and turned inwardly at substantially right angles thereto as indicated in Flgs. 2 and 4. In use, however, these tongues or fingers 22 are bent back to engage the interior of the shade, as most clearly shown in Fig. 1 and in this manner the clinch ring is securely connected to the lipless opening of the shade inasmuch as the flange portion 16 rests upon the exterior of the shade and the tongues or fingers 22 are adapted to engage the interior of said shade.

The fiber washer or lining is securely held in place between the return bend 17 and the annular flange portion 18. In use the fiber lining rests directly upon the incandescent lamp as most clearly shown in Fig. 1 when the threaded end thereof is screwed up into the socket and in this manner the shade is securely supported.

By the employment of the fiber lining safety is assured and furthermore a certain amount of resilience is obtained between the ring and the threaded end of the lamp. This connection is therefore to be preferred to one lacking this advantageous feature. Furthermore, by means of this fiber collar a tight grip can be obtained and which will permit the shade to be supported either in a depending position or extending upwardly with the support at the bottom.

It will thus be seen that I provide an exceedingly cheap and simple type of clinch ring and which will effectively carry out all of the objects for which it is intended.

Having thus described my invention, what I claim is:

1 A device of the kind described comprising a metallic ring having a flange adapted to engage the exterior of a glass shade, a plurality of bendable tongues adapted to engage the interior of said shade, an intermediate inwardly projecting flange and a fiber ring seated upon the said inwardly projecting flange, the interior diameter of the fiber ring being less thanthe interior diameter ofthe inwardly projecting flange.

2. In a device of the kind described, a metallic ring having a. flange adapted to engage the exterior of a glass shade and having a plurality of bendable tongues for engagement with the interior of said shade, said metallic ring being formed with an interior groove and an inwardly projecting flange and a fiber ring fitted into said groove and resting upon said flange, the internal diameter of said fiber ring being less than the internal diameter of the inwardly projecting flange.

8. In a device of the kind described, the combination with a shade of a metallic ring fitted in the top opening of said shade, said ring comprising an outwardly extending flange adapted to engage the exterior face of the shade, an inwardly projecting flange and a plurality of integral bendable tongues adapted to be bent into engagement with the interior of the shade, a fiber ring held within the metallic ring and resting upon the inwardly projecting flange and an electric lamp having its threaded end passing through said rings, the fiber ring contacting with said electric lamp.

4:. The combination with a lipless shade, of a metallic collar adapted to engage the exterior of said shade, an insulating ring held in wedging engagement with said collar, said ring having a radial notch, said collar also having bendable tongues for engagement with the interior 01 said shade.

In testimony whereof, I hereunto aflix my signature.
